Good thing she's got you! This forum is both a blessing and a curse depending on if you let it control your decisions. LOL. The hardest part, to me is the number of folks who post info/advice that they've gotten 2nd hand as being fact/gospel and others accepting it without a second thought. I try to be careful about what I say but don't always succeed.

I like your answer!

First of all, thanks for everyones feedback.
Regarding contacting Lexus Corp., I just figured id give it a shot, being that thought the car is 8 years old, it hasn't been driven much. Plus its their flagship vehicle (which I kindly pointed out) and really...who in the world WANTS to pay $3k+ for a control arm repair?
Anyways, it does indeed show they car about their customers and they stand behind their product.
Double, you know, Tee and I were kind of speaking about that the other day...about how on his last LS with high mileage, his tech told him that he needed new arms, but he couldn't really feel anything wrong while driving. So he continued to drive it. It was a discussion but I soon forgot about it and continued on my quest to research replacement options..
But you've made me rethink about it. To be quite honest, there are a few things that I could take care of that hold a higher position on the "priorities" scale... and I do have a second car.
I am now beginning to consider waiting a bit. I know that uneven wear can begin to occur on the tires once it begins to get bad, but I think im a little ways from that point, as the tires are brand new.
Edit: The other thing is I'm also having the "you gotta get it taken care of" voice that swfl has... I feel as though it needs to be done bc if I don't something else will go wrong. Thinking I'll wait a bit though...
I'll need an oil change soon, questioning whether I should mess with the trans fluid as its nearly 70k miles old, diff fluid drain and spark plugs.

Just had my '10 460 w/70,000 miles at Toyota for it's first transmission drain and fill. It cost me $120 with 4 qts of fluid. I had them draw me a sample for analysis. It's very dirty looking. Glad I did it. Will have results of analysis from Blackstone in a couple of weeks.

Default **update**

So today I brought my LS to an indy that I've been letting work on my Honda for the last 4 years.
Pretty knowledgeable, very, very fair and a great guy.
He took it in and raised it up and we both looked around beneath the car. He immediately mention how the suspension on this car was incredibly well crafted, as he'd never been underneath and LS before.
I showed him exactly what Lexus had shown me: the bushing in the upper control arms. Like Doublebase had said, once I stood there with the shop owner, with a bar and really observed the bushings, not only were they not that bad, but not loose what so ever. Uppers, lowers or rears.
Indeed there where tears in the uppers like I saw, but far from bad shape.
He then put the car down on the ground and ran the car, slowly, forward and backwards so he could replicate the "thump" sound when breaking, and he could hear it. He even had a guy on each side of the car watching the upper bushings to see any shift movement when he was doing so...nothing.
He concluded that though he didn't see anything wrong, he's not exactly sure where the sound was coming from, but to him, it wasn't the UCA's. His advice was to let Lexus fix it, or me get my own parts and he charge me $350 for labor, which is $745 and Lexus wants $860. I may as well go with Lexus.
As I drove away, I aggressively applied my brakes again a few times..and it occurred to me...could it be the brakes shifting...??
Or is it that the old OEM bushings are jus designed in a way that you may not necessarily be able to "see" shift/movement in the bushings, and they may be tight, but the inner area of the bushing is worn out enough for that noise to be produced. Simply, its just what a worn Lexus LS 460 bushing does...

A few thoughts...

First of all, nice move contacting Lexus, and I am glad they offered you some relief.

Secondly, regarding the matter at hand ... I would definitely go forward with replacement for a few reasons.

For reference, I had an '08 460L with a bit over 40k miles at the time. It was 2011, before any control arm TSIBs were issued (though the parts had been redesigned already), and while there had been cases out there, control arm bushings were hardly a widespread or well-known problem.

My car had a few untraceable vibrations and noises, and Lexus' field technical specialist (FTS) got involved and worked very closely with the shop foreman and diagnostic specialist at my dealership. They were stellar and kept me updated throughout the process.

Control arms were the "first stop". Upper control arm bushings looked perfect, visually AND when loaded with a pry bar, as you describe. Per the FTS' request, they were removed anyway. Alas, when the bushings were loaded on the bench (in a vise), "they were junk" (and I am quoting the shop foreman).

I could go on, and there were many informative and interesting chapters to what was an 8-month period where every single issue on this car was resolved to my satisfaction (again, some of these problems are now more broadly known, but in many ways, these gentlemen were breaking new ground). However, my main point is that your bushings may be in worse shape than they appear, especially considering your car's age and mileage, and given what I learned with my previous LS and that you have this option, I would advise going with the redesigned parts at this point.

caha; great to see you, and as always, thank you very, very much for for valuable insight.
Everything you stated was very relevant and helpful.
With this event happening though, it is now making me thing about purchasing either a Lexus warranty that is available to me via the dealer near me, -4/50k ~$26/2700 (not exclusionary), a Route 66 warranty 4/50k, $1800 (not exclusionary), I quoted Carchex but it's not worth mentioning at 3/36k, $2400 (with electronic pckg, closer to $2800, (exclusionary).
I am DIY, however I'm honestly not sure how deep my skill set goes, and I really dint wish to "practice" on this car lol! It'd be forpiece of mind at this point, and I do now have the other arm bushings and their age floating around in my head...
I have been told from a few trusted people that the car, over all should be ok. But in all honesty, this situation has y mind going a bit.
Feedback, as always is welcome.

I bought my '10 LS 460 about 6 weeks ago and noticed a clunk when braking hard at low speed. Because my nearest Lexus dealer is 100 miles away, I brought my car to a Goodyear shop for a once over, mentioning to check the control arms. All looked good to them, but it was a complimentary service, so I wasn't convinced. Fast forward 4 weeks and I brought the car to a Toyota dealer for a Xmission fluid drain and asked them to check the arms. They said the lowers were bad. Again, not convinced they did a thorough inspection. So, today I drove to Lexus and just got the call that they're replacing ALL front arms under CPO warranty. When asked about the rear, he said they don't get many of those. Not totally convinced there either, but I've got three years of warranty for them to go bad as well.

Default Update: Upper Control Arms

So, as I have stated in another thread, I had Lexus replace my 4 upper control arms on 12.28.15.
Though it was a bit of a fiasco, it was done and the goodwill gesture was honored, even though it was offered 5 months ago.
Just to reiterate: once Lexus offers goodwill, there is not an expiration date.
When I went to pick up my car Monday afternoon, I stood and spoke with the SAM for a a good few minutes, discussing in great detail what transpired and what I didn't appreciate about nearly the entire ordeal.
He told me that once Lexus Corporate offers a goodwill, it's in their system for 30 days.
Once that time frame expires, he receives an "alert" to contact corporate to update them on the status: if it's been used or not.
He says when he spoke to them back in August, they said that once they learned that the offer hadn't been taken/used, the inquiry was "closed". But what he told me on Monday versus what he told me on Saturday, was that, all that meant was that a phone call would need to be placed in order to re-initiate the process, or, in my experience, make sure the offer still stood. But as I stated, LC stated that once Lexus offers goodwill, it does not expire.
Secondly, because of the dumb aftermarket wheels I have on my car (the wheels that came with it when I purchased the car), the SAM told me he couldn't align the vehicle because of the spoke offset, and the alignment attachment wouldn't fit on the wheels.
It was already late in the afternoon and places were closing and it was snowing badly, and I still had to get ready to travel the next morning.
He goes on to tell me that his master tech told him that the alignment seemed to be pretty spot on, and that if it's out of spec, it's not by much.
He also claimed that on the LS, of the job is done correctly, maybe 2 or 3 out of 10 would need an alignment.
He asking said that my travel shouldn't be affected, and if I wanted an alignment for piece of mind, to get one. He recommended a few places and that was it regarding that topic.
Lastly, referencing the control arms, I asked him about the visual inspection findings on my lower control arms and rear control arms.
He said that he hardly ever see's or hears about rear CA issues on the LS.
As far as my 4 lowers, he said that there is light wear, but he/the tech couldn't classify them as needing repair, but it was documented to keep an eye on them.
He also said that, regarding the new revision of the UCA, that they are a high density poly bushings. I was surprised when he said that.
I had a lengthy on-going conversation with the good people at FIGS (great, great guys there), and what made me decide against their poly bushings was my worry about squeaking (bc I'm in a cold region), and to grease them, you have to remove the arms to do so.
I just didn't like the idea, but another member here in our forum has had Super Pro bushings for 8 years and said he has had zero issues.
I went ahead on my 10+ hour road trip, and though the ride was a little smoother, the vibration was still there at 73-80mph, but it wasn't as apparent, and as Doublebase said, I have a slight pull at highway speed.
I'm currently getting a tire rotation, alignment and RFB at a tire shop, so we'll see how it feels after they're done.
Once I get back home, I'll take a few photos of my old arm bushings and post them here.
Again, thanks for everyone's input and HNY!

Nice, thanks for sharing that story.

Interesting about the alignment issue with the dealer. I had a similar situation with my previous car due to different offsets and this is the reason why I'm so paranoid about getting the exact offsets with any aftermarket rims I purchase for my Lexus. I hate dealing with any hassles.

Also, I had a pulling issue on my previous car as well. Alignment was in good order, but the tires were a few year's old, with roughly half of its tread life remaining. As soon as I replaced the tires that pulling issue went away completely so my tires caused that issue for me, which was surprising.

The tires I had were Michelin Pilot Sports A/S. I went with Pirelli P7+.

It is amazing what new tires can do...they can make the steering feel tight again, they can solve some pulls, they can eliminate some noise and obviously make the car feel more stable.

I really think when we're talking about 7-8 year old cars, there's only so much you can do. Realistically every single rubber bushing in the vehicle would need to be replaced to make it drive like new again. I'll tell you right now, there's not many cars on the road that are 6 plus years old that drive perfectly straight

I find myself caring about my car's oil and engine a lot, when the fact is, most engines will far out live the rest of the car.

Interesting and very true.
After driving the car post the rotation, alignment and balanced, I can honestly say that the car is a bit more quiet, very smooth, however I still have a small shimmy at 75mph.
But overall it is a drastic difference.
I also meant to mention that, like Doublebase said after his repair, my braking was much smoother.
The car definitely drives/handles better.
I'm thinking the lowers may be the culprit of the light shimmy, but who knows.
All in all, I'm satisfied.
Oh, and DB, Lexus charged me 3 hours per side, totalling 6 hours!
After reading your write up, all I could do was shake my head...

No problem.
Just glad I could share my experience with the family, and hopefully help someone.
I forgot to mention that my car actually was actually pretty out of alignment spec.
I forgot the numbers and I assumed they'd attached the report with my receipt, but they didn't.
I'd like to have it so I'll probably swing by on Sat.
But my alignment and balanced was off, and tires are in pretty good shape.

Well don't feel bad, you got your arms for free and there's always the chance something could go wrong when you put them in yourself. The very next day after I did mine my legs were killing me, working on the floor was no fun...all the getting up and down, stuff really wore me out.

And I tend to agree about those lower arms...unless you replace all of them you won't really know if it will take care of that shimmy/pull. Like I said, I did six of them, and it was a big improvement, but I do wonder if I should have done all 8. I'll probably do the lower rears in a few months.

Are all 8 in the front end or front and rear combined?

I need to do mine but not sure how what I need. I'm not in warranty on my 08. My local shop said 4 lower front n rear (not rear on the car). Never said there were upper.
